• Abstract:
  Turning movement (TM) counts are used for a variety of intersection analyses, including traffic operations analyses, ; intersection design, and transportation planning applications. For many planning and design applications, especially in the case of ; proposed future improvements to an intersection or even proposed new intersections, future year TM counts are needed for the ; analysis. Accordingly, there is a need to forecast turning movements at the intersection. ; The purpose of the research was to inventory and review the methods used to forecast intersection turning movements. ; The effort was limited to a literature review and a limited survey of practitioners to determine methods currently being used to ; make such forecasts. ; Based on this limited review, it was found that the state-of-the-practice for estimating turning movements is based on ; using growth factors to project link volumes and TM counts. In many cases, engineering judgement is used to account for special ; conditions or to accommodate known or anticipated land use changes that may significantly impact turning movements. The ; implication, therefore, is that although there are similarities among methods used by a variety of organizations for a variety of ; purposes, there is no identifiable preferred means of estimating turning movements. The most definitive technique found is the ; procedures described in the National Cooperative Highway Research Project (NCHRP) Report 255.
